The LS-7 Exhaust manifold will bolt directly onto a stock 2005 as long as U use the collector tubes with cats, correct?? What kind of power increase with just these bolted up? Any gusses or has someone done it and dynoed it???
Also has anyone used the OBX long tube header system on e-bay for $799 w/hi flow cats? Any feedback there also please?:burnout:
Thanks Very much

You use the manifolds, cats and H pipe that can either be reduced to 2 1/2 or replace the rear pipes and mufflers w/3" parts for a Z06

Most dynos have shown about 20 or so HP and about 15 torque.

In a few months, I'll be taking off my Z06 that I reduced and replacing it them with LGs street series and then doing a dyno again.

I'll be interested to see what you get outta that.:sm_party:

On several other forums, guys have mixed results. although they are half of what new others are. if the tolerances on the gap at the block are off just a little, it makes for some work to get it right, easily eating into the $$savings, dont forget the aggravation of having to take them off and have them fixed.

Texas Speed in the lubbock area has some good prices on theirs. sorry, i have no knowledge of their workmanship
